The Lotka–Volterra model of cyclic competitions among three species with noise was investigated by numerical simulations. Our results indicate that the multiplicative noise is responsible for the alternately sinusoidal competitive oscillations of species, the optimizations of response of the system via stochastic resonance, the spatial patterns and the temporal oscillations of the spatial correlation coefficients.
